Divided and this application tiled .Tune 30,

1909. Serial No. 505,248.

To all whom it may concern Be it known that I, MARSHMAN 7. HAZEN, acitizen of the United States, and a resident of New York, count)r andState of NenT York, have invented certain new and useful Improvements inCarriages for Type-Writ ing Machines, of which the following is a full,clear, and exact description.

This invention relates more particularly to linelock mechanism for.typewriting machines, and is a division of my pending application SerialNo. 439,967, tiled June 23, 1908.

The primary object of the invention is-to provide simple and eilicientmeans whereby the carriage may be positively locked at the vend of aline and then permitted to have a further movement in case it desired toadd one or more letters or characters to finish a Word at the end of theline, and then `again automatically lock the carriage against furthermovement.

A Vfurther object of the invention is to provide simple and' efficientmeans having a part held to the carriage and movable therewith, andanother part not movable with the carriage in its letter spacingmovement andv which is adapted to be engaged by the firstmentioned partto stop or limit the action of the keys and thus lock the carriageagainst movement at the end of a line.

With these and other objects in view, the invention Will be hereinaftermore particularly described with reference to the accompanying drawings,this specifi-cation, out in the claims tion.

In the drawings, Figure l is a longitudi-l nal section of one form ofmachine embodying the invention. Fig. 2 is a rear elevation of themachine. Fig. 3 is an inverted plan which form a part of and will thenbe pointed at the end of the descrip- .view of the carriage removed fromthe machine, showing one forni of line-lock together with a part of theescapcment mechanism. 'Fig 4 is an enlarged vertical section through apart of the carriage, showing a part of the escapement mechanism: andFig.` 5 is a fragmentary view, showing a differentform of means forlocking the carriage at the end of a line.

The frame 10 may be of any suitable construction and'msay be providedwith a plurality of bars 11 to which are pivotallv held the key-levers12, and these key-levers ll2 are normally forced in one direction by thesprings 13 and at their inner ends are connected by links 14 to thetype-bars 15. These type-bars 15 are pivotcd at 16 to a bracket 17, andhave their type-heads 18 adapted to engage the Work passing about theplaten 19, which latter is suitably supported on the carriage 20.

As an escapement mechanism and means for operating the same the carriage20 is provided with a rack-bar 21 under the same, and this rack-bar hasthe usual ratchetshaped teeth in which are adapted to move theescapement pawls or dogs 22 and 23, Figs. 1 and 4., one of which, as 22,is'xed and the other, as 23, is movable, and both dogs are adapted topermit the carriage to move the distance of a single tooth as usual whensaid dogs are moved laterally transversely of the rack-bar. The dogs 22and "D are carried by an arm 24 which is pivoted atV 2.5 to the carriagebed 26 and has its opposite end, as 27, guided in a slot- 28 of abracket 29 so as to permit the dogs to be moved laterally of saidrackbar allowing the carriage to escape one tooth at a'time and causingthe dogs to be swung in an arc of a circle across the face of the rackin the same plane as the rack instead of in a direct line thus makingthe dogs engage the rack teeth at one point instead of along the entiresurface thereby materially reducing the Wear and friction therco. Aspring as 30 is arranged on the carriage bed` Fig. 1.1-, and has one endpassing through the fixed dog 22 and is so arranged that it will onlyforce the dog and t-he arm in one direction, and secured to the arm 24is a stop 31 which is adapted to engage a projecting part 32 of themovable dog 23, in order to limit itsv movement, the: said dog beingnormally held against movement in one direction by the spring 33, and inthe opposite direction by a spring 34, though instead of the two springsa single spring may be employed he escapement may be operated no matterwhat position thc carriage is in. This is secured by arranging a movablebar 35 of the escapcment-operating frame transversely of the machine. Acollar or projecting part 36 located on the bar 35 is Patented Apr.itat, i914.

if desired.`

adapted to engage the head 27 of t-he arm 24 so as to move theescapement pawls against theaction of the spring 30. The bar 35 is heldin the upper end of the levers or arms 37 of the'cscapcment frame andsaid arms are pivoted on opposite sides of the ma chine to a,transversely-extending rod or bar 38, each e'of said levers or arms 37being provided with! a vertical slot 39 at the upper Vend thereof.fbellprank or angular' lever 40 is pivoted at 41 to a part of themachine frame lon each side thereof, and has one end, as by a screw 42,`guided in the slot 39 of the lever or arm 37 and its other endconnected by a link 0r rod 43 to a universal bar 44. This universal bar44 extends transversely of themaehine over each key lever so that aseach key is depressed it will raise the bar 44 and move the bell-cranklevers 40 on their pivots 41, and by means-of the shoulder screws 42 inthe slots 39 of the levers 37 Will throw the escapement-moving bar 35outward and thereby move the escapement arm 24 carrying the'pawlsagainst the tension of the spi1ng3t. Theparts thus far described may beoli" any desired construction.

It is desirable to lock the carriage at the end of a line, and it isalso desirable to permit the carriage to have a maximum throw to addoneor two letters to any of the lines in case the Word is not finishedproperly. This may be e'ected in various Ways. As shown, Figs. 2 and 3,the arm 45 to which the flexible connection 46 from the escapement drum47 is attached, and which rings the bell, has a dog or locking device 48pivotally held thereto and normally pressed in- Ward by a spring 49.This device extends outward on opposite sides of its pivoting point,Figs. 3 and 6, one part, as at 50, to serve as a handle and the otherpart, as 51, being provided with a subsantially U- shaped slot 52. A rodor device 53, Fig. 3, is rotatably held in the brackets 54 secured tothe carriage bed and under the same, and said rod has one end 55 bent tolie normally lin a horizontal plane, and its other end 56 bent or madeto extend at right angles thereto so as to project above the car riagebed on the outer surface thereof, as shown in Fig. 2. The rod mayy alsobe bent or formed With a part 57 to position the ends 55 and 5G, thelatter end being adapted to be engaged by the detent or device 48carried by the arm 45 and movable with the carriage, While the end 55,when the rod is engaged by the device 48, isrforced down- Ward on theouter side of the bar`35 so as to prevent thesame from being moved bythe keys, thus preventing the eseapement being operated and locking thecarriage. If the device48 is released by the handle end 50, the carriagemay still b e moved a certain number of spaces until the rod is againengaged by the shoulder 58 of said device, the dis `tance the carriageis permitted to move being determined by the length of the slot oropening' in the device or the distance between the two abutments. Therod or element 53 is normally held in one position by a. spring 59, andits end 56 is first engaged by the end of the device 48, and when thelatter is released, as can be done very readily, the said end 56 willenter the slot in the device until the shoulder or abutment 58 engagesthe same, and depresses it when the carriage will be positively locked.By this means additional letters may be printedat the end of a line tocomplete a Word if desired and the carriage again automatically stopped.

F ig. 5 shows hoW the end of the device 48, instead of striking the end56 of the rod 53 is made to engage one end of a pivoted arm or lever 00.This arm or lever is pivoted under the carriage bed, and is forced inone direction by a spring G1. This lever has one end adapted to beengaged by the device 48, and has its inner end adapted to be forced inthe path of movement of the arm Q4 carrying the escapement pawls 22 and23, and thereby ,prevent movement thereof through the bar 35 andmechanism hereinbefore described.

lhle I show and describe features othel` than those relating to theline-lock mechanism, such features are not claimed herein as they formsubject matter of separate copending applications among which are feedmechanism, Sr. No. 499,893, tiled June 3, 1909; line-spacing mechanism,Sr. No. 499,874,1tiled June 3, 1909; and carriages, Sr. No. 439,907,filed June Q3, 1908. y
